Study on the Technique of Sea Fog Detection Using MODIS Data
Pages: 70-73
Year: Issue:  2
Journal: Hydrographic Surveying and Charting

Abstract: 以MODIS/TERRA卫星为数据源,以2006~2009年黄渤海区域五个台站的实况资料和部分海测资料为依据,选取了23幅有雾天气卫星云图为样本,对卫星36个通道进行了相关性分析实验,通过该实验实现了海雾特征通道的选择.对特征值与日地关系因子进行了相关性分析实验,讨论了日地关系因子对海雾特征值的影响,提出了特征通道特征值的订正方法.在此基础上,运用阈值法进行了海雾检测,取得了理想的海雾正检率.
